GEORGE A. MILHOLLAND, OF PITTSBURG, PENNSYLVANIA.

TRESTLE.

Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed April 12, 1909. Serial No. 489,513.

To all whom it may concern:

Be it known that I, GEORGE A. MinnoL- LAND, a citizen of the United. States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Trestles, of which the following is a specification.

This invention relates to certain new and useful improvements in trestles and similar supports, and the invention has for its principal objectto provide a folding durable structure that can be advantageously used as a household article, for firmly supporting an ironing board, platform or trimming board. While primarily designed as a household adjunct, the trestle or support can also be used by paper-hangers, painters and similar artisans for retaining a board or platform in an elevated position.

Another important object of this invention is to provide a simple and inexpensive structure that can be folded to occupy a comparatively small space when not in use, the structure in a collapsed position being easily handled.

The above objects are attained by a trestle that can be safely used for many purposes, and in order that the invention can be more fully understood, reference will now be had to the drawing forming part of this specifieation, wherein like numerals of reference designate similar parts throughout the several views, in which:

Figure 1 is a side elevation of a pair of trestles supporting a board or platform, Fig. 2 is an enlarged elevation of a trestle, partly broken away and partly in section, Fig. is a plan of the same, Fig. 4 is a side elevation of a folded trestle, partly broken away and partly in section, Fig. 5 is a perspective View of separated parts of the trestle, and Fig. 6 is a similar view of the connecting member forming part of the trestle.

As the trestles are identical in construction, I deem it only necessary to describe the detail construction of one, but desire it to be understood that two or more can be used for supporting a board or platform 1. Each trestle comprises members 2 and 3, the member 3 being of a greater length than the member 2, with said member 2 of a sufficient length to provide an A shaped structure when the trestle is in use. The upper and lower ends of the member 3 are cut away, as at 41, to accommodate cross heads 5 and 6,

said. cross heads being grooved as at 7, to receive the ends of the member 3, whereby the front and rear sides of the heads will be flush with the same sides of the member. Bolts or screws 8 can be used for lirml y connecting the heads 5 and (3 to the member. The upper edge of the member 5 is beveled, as at t), and the lower edge of the member (3, as at 10, these beveled surfaces being parallel, whereby when the member 3 is placed in an inclined position upon a floor or similar surface 11, the board or platform will be retained in a horizontal plane parallel with the floor. Member 2 is constructed similar to the member 3, but with only one cross head 12, adapted to cooperate with the cross head (5 in forming substantial braces for the members 2 and The upper end of the member 2 is hinged, as at 1. 1, to the member 3, to provide an Ashaped structure when the members are positioned at an inclination to one another.

To prevent the members 2 and 3 from spreading or completely collapsing from the weight of the board 1 the inner side of the member 3 is provided with a ltmgitudinal strap 15 and loosely engaging said strap is the eyelet end 16 of a connecting member 17, said member being pivotally mounted upon a pin 18, arranged transversely in the upper end of a longitudinal slot 19 formed in the member 2. The slot 19 provides clearance for the member 17 and the strap 15, when the members 2 and 3 are folded, as shown in Fig. 4 of the drawings.

From the foregoing description, taken in connection with the drawings, it will be observed that I have devised novel trestles or supports that can be easily handled and stored away, when not in use, and that the connecting member of the two members composing the A-shaped frame is fully protected and cannot be injured when roughly handled.

l/Vhile in the drawings forming part of this specification there is illustrated a preferred embodiment of my invention, I would have it understood that the detail construction thereof can be varied or changed asto the shape, proportion and manner of assemblage without departing from the spirit of the invention.

Having now described my invention what I clann as new, 1s

1. A trestle, comprising a member, cross heads secured to the ends of said member,

said heads having the outer edges thereof beveled with the beveled edge of one head in parallelism with the beveled edge of the other head, a member hinged to the first 5 mentioned member, a cross head carried by the lower end of said hinged member, said cross head having the lower edge thereof beveled, said hinged member having a longitudinal slot formed therein a connecting member pivotally mounted in said slot, and a strap carried by the first mentioned member and adapted to loosely support said connecting member, said slotproviding clearance for said connecting member and said 15 strap when said members are folded.

2. A trestle, comprising two hinged members, cross heads carried by the upper and lower ends of one member, a cross head carried by the lower end of the other member, one of said members having a slot formed therein, a connecting member pivotally mounted in said slot, and a strap carried by the other member and adapted to loosely support said connecting member, said slot providing clearance for said connecting member and said strap.

In testimony whereof I aflix my signature in presence of two witnesses.
